DUMP-WAGON.

Specification of Letters Patent.

Patented ill, till-l.

To all ac/mm may, concern Be it known that I, THOMAS \Vnronr,

citizen of the United States, residing at Jersey ity. in the county of'l-lndson and State of New .lersejnhave invented a new and useful llurhh-Wagon, of which the tollowing is a specification. i

This invention/relates to dump Wagons and morei particularly to motor driven Wagons of this character, the principal object of the invention being to provide means wherehvtlie motor used for propelling the vehicle can also be used for elevating'the body relative to the chassis of the machine.

Another object is to provide a vehicle of this a 'acter in which the body can be elevated either by means of the motor or by hand power,

A further object is to provide improved mechanism for transmitting motion to the lifting elements from the drive shaft of the vehicle.

Viith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed. can bernade Within the scope of what is claimed, Without departing from the spirit of the invention.

In the accompanying drawings the preferred town of the invention has been shown.

in said'draWingsF-Fignre 1 is a side elevation of a vehicle having the present improvenients combined therewith. Fig. 2 is a plan view of the mechanismconstituting the present invention, Fig. 3 is a side elevation of said mechanism.

Referring to the figures by characters of reference 1 designates the chassis of a niotor vehicle, said chassis normally supporting a body 2. This body may be provided with elevating arms 3- connected to the body by links at, the lower ends of the arms being mounted to travel along inclined rails 5. The means for lifting the bodyotl' of the chassis does not constitute any part of the present invention and the structure shown for this purpose has already been set forth in Patent No. 1,019,211 issued to me on March 5, 1912, although it is to be under stood that any other desired mechanism may be employed desired. A winding drum (5 is mounted for rotation upon the chassis and has chains, cables or other flexible elements 7 secured thereto and adapted to be n'onnd thereon these flexible elements being attached to the lower ends of the arm, :3 so that. when the said elements are Wound upon the drum. the lower ends of the arms 3 will be drawn toward each other and said arms will thus operate to lift the body 2 oil of the chassis l. I

The longitinlinal-drive shaft of the motor vehicle has been indicated at $3" and serves to transmit motion from the motor. not shown, to the propelling wheels of the vehicle. vided. In order to utilize the propelling; motor for the purpose of elevating the any 2 oi the wagon, it is necesary to secnre a gear 9 to the shaft 8. This gear meshes with a larger gear 10 secured to a sleeve 11 mounted for rotation Within a bearing 12, there being" a clutch member secured to and revohiblc with the sleeve. A shaft 1% jonrnaled in the sleeve and has a sorocket '15 secured to it. there being a clutch member 16 i ithered on the shaft and adapted to he shiftedinto and out of engagement with the clutch member 13 by means lover I? which can be readily reached from one side of the vehicle. Sprocket 15 is adapted to transmit motion through a chain 38, to a sprocket 1'9 secnredto a counter shaft there being a small ear 21 feathered on the shaft and adapted to be shifted longitudinally thereon by means of a lever i" dapted to mesh 'vith a are gear 23 secured to the shaft 24 on which lruin 3 is secured and another small gear 25 meshes with gear 23 and has a central angular stud or projection 26 whereby the said year can be rotated readily by placing a crank in engagement with the stud.

It is of course to be understood that under normal conditions, the clutch members 13 and 16 are out of engagement with each other and, therefore, the shaft 8 although rotating, will not actuate the winding mechanism. Only the gears 9 and 10 and the clutch member 13 will rotate during the actuation ort shalt 8. Should it be desired to elevate the body 2 by hand, as ordinarily, lever 22 is shifted so as to disengage gear 21 from gear 23. A crank or other suitable device is then placed in engagement This shaft is the one usually pro-- lllll' with stud 26 and the small gear 25 is rotated so that motion Wlll thus be transmitted' to the large gear 23 and thence through shaft Ql to the Winding drum (3.

Should it be desired to elevate the body 2 by utilizing the power of the motor on the vehicle, the shaft (5 is kept rotating; while the nnichine is standing still and, after shifting gear 21. into mesh With gear 33, lever ii is shifted so as to bring the clutch member ll; into engagement With the,rotatin clutch member 13. Motion \villtho'refore be transmitted from shaft 8 through gears 5t and 10, clutch members '13 and 16 and sprocket 15 to chain 18 and this chain will drive sprocket 19, shaft 20 and gear 21 which, in turn, will actuate gear 2-3, shaft and drum {3. As soon as the body has been raised to the desired elevation, the clutch member It is shifted out of engagement with clutch member 13.

Any suitable mechanism can of course be provided for holding the body raised after it has been elevated by means of the mechanism described. Such means, however, does not constitute any part of the present invention.

When the holding means is disengaged from the elevating mechanism, the body of the wagon will gravitate to it initial position, this movement causing the operation of the mechanism to reverse and the cables 7 to unwind from the drum (3.

What is claimed is:-

1. The combination with a 1notor.prepelled vehicle including a longitudinally disposed drive shaft, a vertically movable body, and lifting devices for the Jody, of a gear, means upon the same shaft therewith and actuated thereby for operating the lifting devices, a hand actuated gear eonstantly meshing with the first named gear.

another gear shiftable into and out of mesh with the first mentlonec gear, a transverse shaft, a clutch member feathered thereon,

' meansrevoluble with said transverse shaftfor transmitting motion to said shift-able gear to rotate it, a driving clutch member, means for transmitting motion thereto from the drive shaft, and means for shifting one of the clutch members into and out of en gagenient with the other clutch mei'nber.

2; The combination with a motor propolled vehicle including a vertically movable body and lifting means cooperating with the body, of a longilu iliual drive shaft for actuating the vehicle. a transverse winding element interposed between said lifting means, o positely extending flexible means connected to the Winding element for actuating the lifting; means, a gear revoluble Wi 'h the winding; element, said gear and element being mounted upon the same shaft, a hand actuated gear eonstai'itly meshing with said first mentioned gear, a counter shaft, a

gear feathered thereon, means for shiftingsaid r into and out of mesh with the first named gear, a revoluble sleeve, a gear thereon, a gear upon the drive shaft constantly nieshi'ng,- with the gear upon the sleeve, atransverse shaft journaled within the sleeve, a clutch member carriedby the sleeve, a clu'cah member feathered upon the transverse shaft, means for actuati 'said feathered clutch member, and means for transmitting motion from the transverse shaft to the counter shaft.

In testimony that I claim the foregoing as my own, l have hereto affixed Inv sig na ture in the presence of two witness THOlvlAS (Hi (-i HT.
